Fundición Paipote

Fundición Hernán Videla Lira better known as Fundicón Paipote, and formely known as Fundición Nacional Paipote, is a copper smelter plant 8 km southeast of Copiapó in Chile's Atacama Region. It operates with a Teniente Converter smelting technology and produces copper anodes made of 99.6% of copper. The smelter is owned by ENAMI and has been paralyzed since February 2024 for a major overhaul. At the time of paralization the smelter generated economic losses for ENAMI.

It is classified as a "custom smelter" as it does not depend on ore concentrate from a particular mine nor does it lie next to one. It was established in 1952 with the stated aim of smelting ores of small and medium-scale mining in the Atacama Region. Besides copper it also processes ore concentrates of silver and gold.

In 2015 it had a capacity to produce 84,000 metric tons of copper yearly making it the smallest of Chile's seven copper smelters.

The smelter has been criticized for exceeding on certain occassions by far (almost 500%) the sulfur dioxide emission cap set by environmental regulations in 2019 which is 350 μg/m3 SO2 per hour. In addition there were accusations in 2021 of doctoring of smelting process data.

It is named after Hernán Videla Lira (1903–1982), a mining businessman and politician .
